Hispasonic.com had a little talk to Olivier Gillet, the creator of the Shruti-syntesizers. He revealed some information about the future of Mutable Instruments and his thoughts on what makes a good synth.

Next project (september/october): the MIDIpal, a small, inexpensive, MIDI processing
unit, running algorithmic transformation on the MIDI notes (arpeggiation, harmonization, delays) along with more traditional filter/splitter/monitoring things. Something you’ll want to stick between anything with a keyboard and anything with an audio out in your studio :) This is the first project that will be industrially manufactured – though the first batch will be available as a SMT kit.

A new Shruthi-1 filter board (MS-20 clone).

A variant of the Shruthi-1 digital board that will replace all the digital oscillators by 12-
bits sample playback from a SD card (and will probably do sampling too).

Also, from the forums at mutable-instruments:
“MIDIpal kits will be available in october and a new batch of Shruthi kits in november.”
